Rated 4 out of 5 by Oldun from Mostly goodI used on about 1000 sq ft of lawn. My lawn is 30 years old and the soil is dobe clay. None of the original compost remains in the soil It took me about 3 hours. I am 74 but in pretty good shape. It slots are about 1 1/2 inches deep which I think is about right. It cuts the slots fairly close together so I had to be careful and not be over the same area twice or it striped out the turf. Had to work it back and forth a little to get the depth I needed. It ripped out a lot of the old dry grass and did a reasonable amount of thatching too. I had some weeds hidden under the grass and those were exposed and easy to remove. I expect it will take 4 to 6 weeks for the turf to recover but It really needed it. I have one area where I reseeded within two months. I had to be really careful on that area. I did the job for less than it would have been to rent a plug type and the tool still is like new. very tough and easy to install. Don't do it if you are having a lawn party soon. wait until after. I think it would have been better to do it early spring then follow with heavy fert.

Rated 5 out of 5 by redoak22 from Fishing Bait FinderUse it with the wheels and adjust the wheels to one of many settings to allow the blades to work for you--use it as a thatcher too. Self cleaning blades with neutral throttle and a slight roll backwards will roll out all the contents wound up around the shaft. Will run without a cotter pin and didn't even know it until 15 minutes into the job and the blades had a side ways motion while turning a corner--the blade fell off gently without damage. Enjoy the throttle for light to heavy work and little white finger after two hours of steady work. Fun and addicting to use so much you will be draining tanks of gas out of the box. Pulls up top layer vines like chick weed and chews it up with s simple backwards and forwards motion that won't hurt the grass. Never knew Zoysia grass had so much thatch and worms hiding deep inside. These blades popped up all the worms along with the thatch. Grab them fast for fishing before they quickly dive back into the grass.
